smartctl hpt27xx controller with more than 16 devices

[stin9ray]

Limit of 16 devices seems to be hard coded.

The command to retrieve a smart dump for da16 fails:

Controller: High Point RocketRAID 2760A
This controller is advertised as a 16 channel controller that "switches" 24 internal disks.

In my configuration here are 19 disks connected to the controller, all are detected as da0 .. da19.
da0 at hpt27xx0 bus 0 scbus7 target 0 lun 0
da0: <HPT DISK 0_0 4.00> Fixed Direct Access SCSI-0 device
da0: 2861588MB (5860533168 512 byte sectors: 255H 63S/T 364801C)
[...]
da19 at hpt27xx0 bus 0 scbus7 target 19 lun 0
da19: <HPT DISK 0_19 4.00> Fixed Direct Access SCSI-0 device
da19: 953869MB (1953525168 512 byte sectors: 255H 63S/T 121601C)

The command:
smartctl -d hpt,1/16/1 -x /dev/hpt27xx
works as expected dumping all the smart info for da15.

Ok, as far as i could see there is no such limits in the code

ids[0] = m_hpt_data[0] - 1;
ids[1] = m_hpt_data[1] - 1

Is it possible to provide access to affected hw? It is possible that problem is in the driver, not in smartmontools.

[Alex Samorukov]

Sorry, wrong previous comment.

if (!(1 <= disknum && disknum <= 15)) {

set_err(EINVAL, "Option '-d hpt,L/M/N' invalid pmport number N supplied");
return 0;

}

In the code there is a hard limit. Could you please try to change it to 128 and try if it works for you?

P.S. Also hpt interface is outdated, so if it possible to provide some hw with this controller i can convert it to new api and this will improve it support.

[Alex Samorukov]

In SVN revision 3824 maximum disk number is 128. Please test and tell if it works for you.

Should work since r3824, no feedback so far.
